The school sold 200 tickets to play. Student tickets are $4 and adult tickets are $6. If they made a total $930 how many of each did they sell?

65 adult tickets and 135 student tickets were sold.

Step-by-step explanation:

4s + 6a = 930

s + a = 200

s = - a + 200

4 (-a + 200) + 6a = 930

-4a + 800 + 6a = 930

2a + 800 = 930

2a = 130

a = 65

There were 65 adult tickets sold.

200 - 65 = 135

There were 135 student tickets sold.

Check:

4 (135) + 6 (65) = 930

540 + 390 = 930

930 = 930
